I regret to information the Bluesky philosophy community that Michael Friedman, noted philosopher of science and ground-breaking historian of Kant, neo-Kantianism, and logical positivism has died. May his memory be a blessing. #philsci

More generally, we believe this kind of design shows that time is of the essence! Cool insights into the dynamics of cognitive control pop up when you bring participants back for multiple sessions. Huge thanks to my collaborators Rut Zaks‑Ohayon, Yossi Tzelgov, and the incredible Nir Fresco! (fin)

Surprisingly, the impact of task conflict didn’t increase with practiceβ€”performance gains were similar after the first session. We think task conflict is strongest when the conflict is novel. (5/n)

We found that repeating the task over consecutive sessions and across weeks improved response times in both congruent and incongruent trials, but the effect persisted. So, while you do get faster, overcoming interference from the sensory and semantic informational conflict doesn’t go away (4/n)

Beyond the informational conflict in Stroop stimuli, we manipulated task conflict by varying the proportion of word vs. non-word stimuli like ####. A higher proportion of non-word stimuli is thought to create greater task conflict, leading to higher expected interference with task stimuli (3/n)

The Stroop task is a classic tool to study cognitive flexibility. But how does repeated practice influence how we handle the conflict between sensory and semantic information encountered in the Stroop task? (2/n)
